Armagh Observatory by moonlight, with Ursa Major (The Big Dipper) visible just above the Observatory and Capella and The Pleiades off to the right.

The telescope domes visible are, from left, the 1790 dome believed to be the second oldest surviving dome in the world, with its Troughton Equatorial Telescope being the oldest telescope in its original housing; The 1827 East Dome housing the 15-inch Grubb Reflector; The Robinson Memorial Dome completed in 1885 housing the 10-inch Grubb Refractor; and the Armagh Robotic Telescope which can be seen in use here and was completed in 2011.
